This build is based on the class mod Red Fang. While gamma is active, no one will attack you but be careful of aura and splash damage. As for weapons, I mainly use lightshow, gargoyle, plaguebearer, hellwalker and monarch with the matching elements for the job at hand. As for the annointment, the best one is ASA 200% dmg.
The shield I use is mainly a Transformer with action cooldown and the artifact is the Pearl.
My pet rarely die and for the rare time he does, I just wait for the cooldown and my pet revives with ASA.
